Onto the Scholar's Desktop with Firefox Scholar

I first encounted Firefox Scholar (a.k.a. SmartFox) in a Chronicle of Higher Education article by Jeffrey Young, and noted with interest this statement in the article:

For the browser-based software to work fully, however, digital archives must format their books and articles in a way that lets it sort out where elements like title, author, and other bibliographic information reside. Some digital collections already do that, and others could make minor adjustments to comply, says Mr. Cohen.

Unfortunately, there is no reference to what changes have to be made beyond the page on CHNM's wiki describing the project in broad terms. Has anyone else heard of anything?
